hi all,
i am at the part where i have to prep HS 404, 405, 706,707 and 708. The good manual says to flute. Every thread i read in this user forum says the result should be holes need to align and web lay flat on surface while the flanges face up and are at 90 degrees. THe only issue is, my ribs listed above, do that w/o any fluting. They lay straight and when i look at the holes down one flange, they line up.The flange also seems to be at 90 degrees to the web. So, since everyone flutes and i was feeling left out, i fluted one of my ribs to try out. Now after fluting, it bends up. i took most of the flute out to get it to settle down once again. Did I miss something here???? I am sure there will be a time in which i will get a rib that is bent and will need a flute. However, did you guys have similar experience with the above mentioned ribs?
